panel compatibility question
I have a 24 volt off grid system with 4 12 volt BP125 watt panels. Two panels are tied together then go to the combiner box. I was told by my installer that if I wanted to add 24 volt panels I would have to wire them to a separate combiner box and charge controller to do that. My question is could I not just wire each 24 volt panel to the combiner box? I would love to add the higher watt panels that are available in 24 volt vs what I can get in 12volt. Thanks for your help.
